以下是从chkconfig实用程序获得的列表。我想知道这些守护进程中的哪一个可以安全停止而不会丢失任何附加功能？

这可能是一个愚蠢的答案，但就像评论中的每个人都指出的那样，不必要是相对的。这完全取决于您的系统以及您想用它做什么。我不知道是否有人能给你一个完美的答案。
如果你真的想简化你的启动过程，最好的办法就是研究每个守护进程。谷歌搜索每个守护进程，找出它们的作用。然后禁用它。尝试启动。使用你的系统，看看哪些能用，哪些不能用。没有那个守护进程你能活下去吗？它破坏了你的启动过程吗？如果需要，重新启用它，然后转到下一个。
这样做的好处是，你会多次破坏你的系统。反过来，你必须弄清楚如何修复它，并且你会更好地理解 Ubuntu 和 Linux 的工作原理。然后你可以回到这里回答很多问题 ;p
哦，还有，备份。一定要备份。或者你可以听取 Luri 的明智建议，在虚拟机中运行测试安装。
